Detection instrument for automatically detecting longitudinal rigidity

Abstract

The invention discloses a detection instrument for automatically detecting the longitudinal rigidity. The detection instrument is characterized by comprising a base, a clamping mechanism, a lifting mechanism, a test mechanism, a displacement mechanism and a controller, wherein the clamping mechanism, the lifting mechanism and the controller are mounted on the base; the displacement mechanism is mounted in the base; the lifting mechanism and the controller are mounted in a box body; the bottom end of the box body is connected onto the displacement mechanism and is capable of moving leftwards and rightwards; the test mechanism is connected to the upper part of the lifting mechanism; and the clamping mechanism, the lifting mechanism, the test mechanism and the displacement mechanism are all electrically connected with corresponding interfaces of the controller. The detection instrument has the advantages as follows: the conditions for detecting the longitudinal rigidity of a sample can be accurately set, so that the experimental conditions are digital and definite; the phenomenon of poor experimental data reproducibility caused by human factors can be effectively reduced, so that the accuracy of an experimental result is improved; and the test operations of force arm length measurement, pressure application, deflection recording, result calculation and the like are all automatically carried out, so that the labor intensity is remarkably reduced.

Description

technical field [0001] The invention relates to a detection instrument for automatically measuring longitudinal stiffness, which is used for the longitudinal stiffness measurement of steel hook cores, semi-support soles, combined soles and midsole in footwear products. Background technique [0002] When conducting footwear testing, the longitudinal stiffness testing of the shank or the combined sole is a mandatory indicator, and all listed footwear products need to be tested for this item. The original testing instrument is completely manual, including measuring the length of the arm, adjusting the horizontal position, pressing force and calculation (that is, bringing these measured data into the formula for calculating the longitudinal stiffness, and calculating the relevant parameters), etc., especially the clamping force. The size cannot be determined, and different operators may apply different clamping forces, resulting in inconsistent measurement results. This manual ...
